All them all together that equal to 82.638 or 82.64

Herman · Answer 2

82.64

When you're rounding sig figs for adding or subtracting, just match the number of decimals in your answer to the number that you added/subtracted that had the least decimals

In the above problem, that number was 2.34, which went to the hundredth place. This means your answer also goes that far.
